Land Rover Part Number: 4462684 - Secondary Timing Belt Tensioner - Left Bank
4462684 is a Secondary Timing Belt Tensioner - Left Bank. Fitted to the upper timing gear assembly on 4.4 AJ Petrol V8 EFI 220KW and 4.2 Petrol V8 Supercharged engines, this tensioner operates on the left-bank timing belt circuit. It applies and regulates tension on the left-bank timing belt within the upper timing gear assembly, keeping the belt engaged with the gear teeth and limiting belt movement during engine speed changes to help maintain accurate valve timing for that bank of cylinders. Replacement of a worn or failed tensioner is part of timing-gear maintenance where belt condition and tension must be restored to factory specification.
